VEHICLE-HEATER.

Specification of Letters Patent.

Application filed June 24, 1903. Serial No. 162,937.

To rtZZ whom it may concern.-

Be it known that I, ISAAC F. SMITH, a citizen of the United States,residingat Selby, in the county of VValworth and State of South Dakota,have invented new and useful Improvements in Vehicle-Heaters, of whichthe following is a specification.

This invention relates to vehicle-heaters.

The objects of the invention are to improve and simplify the means forholding the heater in position upon the vehicle.

\Vith the foregoing and other minor objects in view, which will appearas the description proceeds, the invention consists in the exact detailsof construction hereinafter described and claimed as a practicalembodiment thereof.

In the drawings, Figure 1 is a side elevation of a vehicle, shownpartially broken away and having the improved heater applied thereto.Fig. 2 is a perspective view of the heater. Fig. 3 is a longitudinalvertical section of the same with the lid or cover raised. Fig. 4 is atransverse vertical section through one extremity of the heater.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1 designates a casing preferably formed of light sheet metaland of comparatively shallow depth. The casing is constructed with twoend chambers 2, through the medium of a central arch 3 formed in thebottom, the sides of the arch and outer end of the chambers convergingtoward each other at an angle of inclination to reduce the chambers atthe bottom, and therein are dis posed oil receptacles or reservoirs 4 ofa shape corresponding to the lower portion of the chambers and havingburners 5 of any approved form. At opposite ends the casing is formedwith offsets or shoulders 6, and thereunder in close engagementtherewith hanger-straps 7 are secured and have angular extremities 8,with horizontally-disposed apertured terminals 9. The ends of the casinghave upper elongated draft-openings 10 and lower draft-apertures 11, thelatter being close to the burners and formed in the inner and outerwalls of the chambers. The draft openings 10 and apertures 11 permit airto enter the interior of the heater at different elevations to assist inthe combustion of the fuel, which will be preferably hydrocarbon oil,fed to the burners by wicks, as in ordinary lamp constructions. Theheater is also provided with a hinged lid or cover 12, which is grated,as at 13, similar to a register-face or cover-plate. Close to the lowerside of the lid or cover a sheet-metal plate or guard 14 is secured andhas a plurality of openings 15 therein. This lid or cover 12 is hingedto what may be termed the back of the heater and may be readily openedto gain access to the interior of the heater. The plate or guard 14prevents the flame from the burners passing up through the lid or coverand protects the garments of the occupants of the vehicle in proximityto the said lid or cover Without materially detracting from the upwardflow of the heat-currents into the body of the vehicle.

The upper terminals of the opposite sides of the heater are formed withoutstanding horizontal flanges 16 to assist in the positive securementof the heater to a vehicle-body. In applying the heater to avehicle asuitable opening is cut in the bottom of the body of the latter and theupper portion of the heater is turned or tilted slightly to insert theflanges 16 through the opening, or the said flanges may be slightlystraightened and afterward bent down over the bottom of the vehicle-body close to the opening, as shown by Fig. l. The angular extremities 8 ofthe hangerstraps 6 will then rest closely against the under side of thevehicle-bod y and are secured by inserting fastenings therethrough tohold the heater below the body of the vehicle and bring the lid or upperportion of the heater practically on a level with the upper surface ofthe bottom of the body of the vehicle at a point directly below and infront of the seat. \Vhen the heater is so applied and secured, the lidor cover 12 may be freely raised to supply the receptacles 4 with oil orto trim the burners or for other purposes, and when the burners havebeen ignited the lid or cover 12 is closed and the heat passes upthrough the guard-plate 14 and the said lid or cover. The occupants ofthe vehicle may readily place their feet on the upper surface of the lidor cover, and the adjacent garments will be shielded from scorching orignition through the construction heretofore explained. When a lap-robeis-used and tucked in around the lower portions of the bodies ofoccupants of the vehicle having the heater arranged therein as setforth, a heating-chamber will be produced and the occupants will beprevented from having cold feet and limbs. In warm weather, when it isdesired to dispense with the use of the heater, the latter may be de.

tached and a covering secured over the opening in the vehicle-body,

The improved heater is comparatively inexpensive in construction, and toaccommodate double-seat vehicles two of the same may be used and theproportions varied to compensate for enlarged spaces to be heated. Byarranging the chambers 52 in the manner set forth it will be seen thatthe oil or fuel contained in the receptacles 4 will always be in feedingproximity to the burners, and the angular disposition of the vehicle inmoving over inclinations or grades or tilting to one side will not inthe least affect the feed of the fuel to the burners.

Having thus fully described the invention, what is claimed as new is Avehicle-heater comprising a casing made of light sheet metal, and formedat its opposite ends with integral oifset portions having air-inletperforations therein, heating means in the casing, a hanger-strapextending beneath each of the perforated offset portions, and havingupwardly-bent ends formed with horizontally-disposed perforatedterminals arranged below the upper edges of said cas- ISAAC F.
